TIE-PLATE.

SPECIFICATION forming part of Letters Patent No. 538,808, dated May 7, 1895.

A lication filed November 23,1894. Serial No. 529,690- (No model.)

To aZZ whom it may concern:

Be it known that I, BENJAMIN WOLHAUP- TEE, a subject of the Queen ofGreat Britain, residing at Morgan Park, county of Cook, State ofIllinois, have invented a certain new and useful Improvement inTie-Plates; and I declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make and use the same,"reference being hadto the accompanying drawings, which form a part of this specification.

My invention has for its object the'production of a railway tie plate ofthat class in which the engaging devices onthe under side of the platewhich enter the tie extend parallel with the grain of the tie.

The invention relates more particularly to that style of plate shown inmy pending application for railway tie plate filed March 10, 1894.,Serial No. 503,111. I

- The invention consists in a combination of devices and applianceshereinafter described and claimed.

In the drawings, Figure 1 isa cr0ss-section of a railway-rail, showingan edge elevation of my plate. Fig. 2 is a plan view; Fig. 3, a

view of the under side of the plate, and Fig.

4 an end elevation thereof.

In carrying out the invention E represents the rail and B the body of myplate. On the under side of the plate as shown in Fig. 3 is a series ofdivided ridges O, C. It will be observed that these divided ridges arestaggered, that is to say, they are not in longitudinal alignment witheach other. On the upper'side of the plate are flanges D, D, formingrail abutting flanges to prevent lateralmovementof the rail upon theplate itself.

By the above construction it will be observed that I have obtained amaximum efficiency for the plate against a creeping of theplate,longitudinally of the tie, while at the same time I have providedthe plate with the transverse top ridges D, D to prevent absolutelylateral movement of the rail upon the plate. The particular form of theflanges on the under side of the plate being divided (into the portions0, O) and at the same time staggered as shown gains for the plate thatessential quality of being able to resist the lateral thrusts of therail while at the same time the advantageous features of having theengagin g devices parallel with the grain of the wood of the tie areretained.

The advantages of this style of construction are more particularly setforth in my above named application, and I would have it understood thatI do not herein broadly claim elongated divided ridges on the under sidenor elongated divided ridges in combination with rail abutting flangeson the upper side since the claims of my above named application broadlycover these features, but

What I claim is- 1. A railwaytie plate provided on its under side with aseries of elongated divided ridges inside the outer edges of the plateand extending when in position on the tie parallel with the grainthereof, and on its upper side with one or more rail abutting flangesextending substantially parallel with the rail flange, substantially asdescribed.

2. Arailway tie plate provided on its under side with a series ofelongated divided ridges extending when in position on the tie parallelwith the grain thereof, said ridges being out of longitudinal alignmentwith each other, and each ridge being out of transverse alignment withthe ridge next adjacent, whereby said ridges are-arranged in a zigzag orstaggered form and the plate provided on its upper side with one or morerail abutting flanges, substantially as described.

3. A railway tie plate provided on its under side with a series ofelongated, divided, staggered ridges extending when in position onthetie parallelwith the grain thereof,'and on its upper sidewith oneormore rail abutting flanges extending substantially parallel with therail flange, substantially as described.
